If your RPi server was previously working with ports forwarded from your Virgin router and your Macbook is now responding correctly to port forwards from the Plusnet router there isn't much to cause your current problem except something about the IP address settings of the RPi. Double check that it...

If you want to get rid of the spaces in the datetime string try using ISO format.

for example:

Code: Select all

tn = datetime.datetime.now.isoformat()

By default this will replace the space with a T

See here for reference https://docs.python.org/3.4/library/dat ... .isoformat

When I do plug in my raspberry pi with any wall charger, my monitor keeps blinking on & off with the message "No signal Please check your connection Please make sure you have read this post, I see you are using a DVI adaptor, this might help you. https://www.raspberrypi.org/forums/viewtopi...

Hi there, For the past year or so I have had a Raspberry Pi ownCloud server on line with Virgin Media, publicly accessible via port forwarding. However this week I switched to Plus Net. The router I have is the Plus Net Hub One, which is essentially the same as the BT Home Hub 5. I have followed the...

I was actually hoping that someone would know the pin outs on the RJ45 connectors. I may just have to fiddle with the connectors until I manage to work out which pin does what. Hi there, I'm thinking of doing a similar thing. I have a bird box which currently reports the temperature http://www.pi-t...

Looking at WebIOPi, it looks like it uses board numbers. To convert from BCM numbers to physical board numbers you can use the attached.

I have a Raspberry Pi 2B and I need a total of 20 output pins. Right now it is working great with 16 but which 4 pins can I use output pins to trigger relays? Using the BCM pin numbering system, the following pins can be used as outputs 2,3,4,17,27,22,10,9,11,5,6,13,19,26,18,23,24,25,8,7,1,12,16,20...

Having something that e-mails out a CSV file of the data on a daily/weekly basis might have some merit. As would creating graphs and mailing (or tweeting) them. Jim, I've been using ThingSpeak https://thingspeak.com/ to plot my Bird Box temperature data, plots can be see here http://www.pi-tutorial...

I would like to find out how I can kill a picamera instance so that I can re-call picamera.start_recording() I currently have a python script that streams video to uStream via a subprocess Pipe. Sometimes the stream/pipe breaks, and I want to restart the stream again. If I try and call picamera.star...

$ echo "ClientAliveInterval 60" | sudo tee -a /etc/ssh/sshd_config
Or client-side:
$ echo "ServerAliveInterval 60" >> ~/.ssh/config

Thanks for your time, however my question has nothing to do with SSH or bash.

I am working on a bird camera project, My aim is to build a python3 script that takes the Raspberry Pi camera module video output and stream it to uStream via ffmpeg. I am aware there is already a resource to do this via a bash script and raspivid https://www.raspberrypi.org/learning/infrared-bird-b...

keithellis

For completeness, I have now solved this
Main issue was the

Code: Select all

while True:
      pass

I replaced this with

Code: Select all

while True:
    camera.wait_recording(1)

In addition thanks to Ben Nuttall I removed

Code: Select all

-framerate', '25',

from the ffmpeg cmdline variable.

Can anyone help me in a method to first of all run the bash script in the above example from Python and THEN fund a way to stop the script so when I want to, I can select a different function in the camera? I have now got a Python script streaming the picamera to a RTMP feed (uStream) without using...

I am planning on streaming a Raspberry Pi camera from a bird box to uStream, Raspberry Pi have a nice tutorial to do this here: https://www.raspberrypi.org/learning/infrared-bird-box/worksheet2/ . This works fine and I have a delay between an event happening and it appearing on the uStream site usua...

Just found it on a SD card I had, must have been release a week or so ago I guess.

What sort of loop? I guess you mean continual rebooting. It may help someone to help you if you record the last few messages on the boot screen before the loop, photographing with a mobile or similar perhaps then you can transcibe. If it's headless you will probably need to attach a monitor of cour...

Yep, I've got the same issue. It works fine with Kernel 3.18.5 but as soon as it is updated to 3.18.7 the Pi fails to boot. It gets stuck in a loop during boot.

Problem diagnosed and fixed.

The display was using GPIO 24. During the course of my soldering the SDA line and GPIO 24 line had become shorted, I replaced the damaged wire and all is now working as expected.

I have had both working successfully one at a tim...

Thanks Andrew, I've added a link to the GitHub source. The second link looks interesting too, I've have to take a look when I get a chance.
